Jacking-back device of discharging opening of intermediate frequency furnace

Abstract

The invention relates to the technical field of intermediate frequency furnaces, in particular to a jacking-back device of a discharging opening of an intermediate frequency furnace. The jacking-backdevice comprises a base. Two parallel guide seats are fixedly mounted at the top of the base. A rotating shaft is mounted on the guide seats in a sliding manner and penetrates through the two guide seats. A mounting plate is fixedly mounted at one end of the rotating shaft. A motor is fixedly mounted on the outer side wall of the mounting plate. An output shaft of the motor is fixedly connected with the rotating shaft. The other end of the rotating shaft is fixedly connected with a limiting block. The limiting block is located on the outer sides of the guide seats. Rack plates are fixedly mounted on the opposite sides of the two guide seats. Two rolling gears engaged with the rack plates are fixedly mounted on the rotating shaft. A jacking-back assembly is mounted in the middle of the rotating shaft and comprises a rotating plate. One end of the rotating plate is rotationally connected with the rotating shaft, a connecting rod is rotationally mounted at one end of the bottom of the rotating plate through a hinge, and the bottom end of the connecting rod is rotationally connected with a sliding seat through a hinge. The jacking-back device is high in practicality and worth of popularization.

Description

technical field [0001] The invention relates to the technical field of intermediate frequency furnaces, in particular to a top-returning device for a discharge port of an intermediate frequency furnace. Background technique [0002] The intermediate frequency furnace is a furnace that uses electromagnetic induction heating. After the specification of the inductance coil and the electrical parameters are determined, its induction intensity is inversely proportional to the distance between the workpiece and the workpiece is in the middle of the induction coil. , this situation has no effect on the workpiece located at the inlet, but the workpiece located at the outlet is reduced in induction intensity, causing the temperature of the inner end surface of the workpiece to be higher than that of the outer end surface. The temperature difference of the workpiece will inevitably increase the difficulty of forging, reduce production efficiency, and even affect Forging quality; the p...

[0002] The intermediate frequency furnace is a furnace that uses electromagnetic induction heating. After the specification of the inductance coil and the electrical parameters are determined, its induction intensity is inversely proportional to the distance between the workpiece and the workpiece is in the middle of the induction coil. , this situation has no effect on the workpiece located at the inlet, but the workpiece located at the outlet is reduced in induction intensity, causing the temperature of the inner end surface of the workpiece to be higher than that of the outer end surface. The temperature difference of the workpiece will inevitably increase the difficulty of forging, reduce production efficiency, and even affect Forging quality; the prior art application number 201420024703.3 provides a top-returning device for the discharge port of the intermediate frequency furnace. The piston rod inside the cylinder pushes the workpiece back into the intermediate frequency furnace. The right power cylinder must be at the same level as the discharge port of the intermediate frequency furnace. When the intermediate frequency furnace heats a long workpiece, the right power cylinder will control the discharge produce obstruction
